About this replacement
Asus ROG Strix G15 G513IH / G513QC / G17 G713QE — 15.48V Li-Polymer Replacement Battery (C41N2010)
This is a 15.48V, 3500mAh (54.18Wh) Li-Polymer cell for the Asus ROG Strix G15 and G17 gaming laptop series. It fits models including the G513IH-HN006, G513QC-HN093T, G513QC-HN033T, and G713QE-HX024T, among 42 additional SKUs sharing the same connector and BMS handshake. OEM part numbers are C41N2010 and 0B200-03890000.
- ROG Strix G15 / G17 platform fit: These models share a 4-cell 15.48V architecture with the same 4-pin SMBus connector and identical BMS negotiation logic — one cell services the full cluster without pinout or firmware changes.
- Bench tested on actual hardware: We ran this cell on the G513 platform and confirmed the BMS authenticated without fault codes, the charge circuit accepted full input from the 200W adapter, and the EC reported correct cell voltage across all four series cells.
- Post-swap learn cycle for the G513 / G713: After installing, discharge fully until the laptop enters hibernate, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap on this ROG platform.
BIOS reporting poor battery health immediately after installing a new cell
The Asus EC reads health data stored in the old cell's EEPROM — when a new cell arrives, that data is blank or mismatched, so the BIOS flags it as degraded. This is a firmware read issue, not a cell defect. Run one full discharge-to-hibernate cycle followed by an uninterrupted charge to 100%; the BIOS recalibrates its health register against the new chemistry. After two full cycles the health status on most G513 and G713 units clears to normal.
Laptop shutting off at 20–30% shown on the fuel gauge after battery swap
The fuel gauge IC on the G513 / G713 platform maps percentage to voltage curves learned from the previous cell. A new cell has a slightly different voltage-capacity curve, so the IC misjudges the remaining capacity. Under full CPU plus display load the real cell voltage drops below the EC's hard cutoff threshold before the displayed percentage reaches zero. Run two complete calibration cycles — discharge to hibernate, charge to 100% without interruption — and the fuel gauge IC relearns the voltage cliff of the new cell, typically resolving shutdown around 15.8V per cell group.
